Abstract
The study aims to evaluate the characteristics of horses’ infestation with gasterophilosis, as well as the effectiveness of restorative measures following the administration of anthelmintic drugs. Gasterophilosis is a parasitic disease caused by the larvae of flies of the genus Gasterophilus, which damage the mucous membranes of the stomach and intestines, disrupt digestive processes, reduce overall productivity, and weaken immune indicators. During the study, horses were kept on pasture and in fattening conditions, and upon detection of gasterophilosis, comprehensive restorative therapy was applied. The interventions included dietary correction, vitamin and mineral supplements, as well as specialized therapy aimed at restoring metabolism. As a result, a clear positive dynamic was observed in metabolic, hematological, and immunobiochemical parameters. These findings provide a scientific basis for effective methods of restoring horses after parasitic diseases, their practical application in farming, and contribute to increased productivity in animal husbandry.
